I was told I had manic depression when I was in high school. Since then I took myself off my meds because I wasn't sure if I would have medical insurance after I turned 18. I have mood swings still but in the past few months I have noticed that I see things moving that I know are NOT moving. I will be watching tv in my room alone and hear a voice tell me I am worthless. I will never be good enough. I have been trying to keep a log of when I hear or see something but I don't always remember to write it down. I space out for blocks of time and can't remember what I was doing.

talk to your doctor!
i have that forgetfulness in me too one moment im going to do something the next i foget and dont know what to do.
In summary, get to a doctor. This kind of thing doesn't get better on its own. If you're broke, look into government psychiatric care and try to get on SSI or SSDI disability (ssa.gov). That could net you Medicaid or Medicare which will make psychiatric care and medication cost little to nothing.
